Bug No. 1, bed bug or close relative (looks like it might be male (or else the black spot in it's "butt" is throwing me off making him look more like a him), not recently fed).

Bug No. 2, Shiny Spider Beetle.

Looks like a female bed bug. Black spot is not indicative. Has to do with abdomen morphology. The rear abdomen of a female is symmetrical, but the male is not.
The other is a shiny spider beetle.

Professional entomologist/arachnologist. I consult on all matters dealing with insects and arachnids, including those of natural history and biology to pest management and forensic entomology investigations.

I knew the black spot was not indicative. What I meant was it was making it appear less “symmetrical” to me possibly due to an optical illusion created by the “black spot.”

And since we’re talking about the “black spot” . . . what would that really be called? Digesting blood / fecal matter (yet to be “expelled” fecal matter that is) / stomach material? Does it have a name while it’s still “inside” the gut?

So that’s why I (incorrectly mind you) thought the OP’s bed bug was possibly a male (it appeared to be more pointy to me . . . and as stated before possibly due to the optical illusion of the “black spot” (at least to me).

Abs in laymen terms , do the females simply have more rear-end curve ? , humm interesting. comparing the two pic's I'm thinking the 2nd one you posted is a recently fed male ( less body & buttox roundness)

I think I get it Lou at least I hope so, the male has a cleft @ the tip of the rear end point. I think I get the point now
But I still wont venture in to sex ID's here, I'll leave that to you'll..
An on another note of education, the book louse was alone but when its family arrived they were book lice ?
